Switches are normally wired into the system and connections on their individual ports dedicated to a single device.

Cisco has an extended MAC list command for the switch, but I’m not sure if it will do what you want.

mac access-list extended name

allows predefined MACs to access specified protocols/traffic on the switch port.

As jinteik says, you can set switches up to allow only one specified mac to use the a defined port, but multiple access lists for the same switch port is not something I have come across before, or even wanted to do.
